Just wondering for you swapers, what your car weighed before and after.
So how much did the LT1 add or drop, same with the LS1, the 6 speed, ect.. ect.. just wondering what the difference is after the swap. (obviusly the power is worth the weight gan :-D )

Both the LT1 and LS1 weigh less then a SBC

The LS1 is about 150 pounds lighter, and it raised my car about .5-1"

The LS1 is an all aluminum engine

As far as weights are concerned, for a general estimate on stock engines it's like this......

SBC>LT1>LS1

Any actual weights.
anyone weigh there cars?
thank you tho, flynlow

Umm, I don't think anyone with an LS1 has weighed there car before and after.....But you take a the stock weight of your car just minus 145-150 pounds from it.......Maybe some with an LT1 will chime in and tell what their car weighs....

For reference

The LT1 is approx 80-90 pounds lighter then your average thirdgen engine, and the LS1 is 65-70 pounds lighter then your LT1

Is there a specific reason you are looking for actual numbers?? Prehaps we can help in other ways since weighing your entire car is not something that gets posted often

i was jsut curios what the weight gain/drop would be if i ended up doing the conversion. It looks like im just gunna have the motor i built (355) shiped to me, and ill look for a T-56 to swap in all at the same time.

is a 350 heavier or lighter than the 305 TBI

how do you go about moving the center of gravity, ect. i want the car to handle like its on rails. i have a lot of work to do first, but i just like to look in the long run...

Most Gen 1 motors will wiehg about the same, so your 305 TBI and 350 will be about identical. A 305 block is a hair heavier but not by much. Lowering your car is a great way to change the center of gravity.

W/driver or w/o?

Nice that must mean mine must be lighter than that. Don't auto trannies weigh 145+ lbs. I also have aluminum heads so I must be in the 3200 range.

scottland

LT1's and LS1's are SBC's

but anyway, LT1's wouldn't nessicarily weigh any less than a GENI SBC. there are plenty of GENI's that have aluminum heads, and in that case, the weight difference is probably none existant.

Drakar

The amount of aluminum headed FACTORY SBC 1's has got to be far far less then the amount of IRON headed ones, but basically you can look at it this way.

L98/LB9> LT1 > LS1

and that being all F-body ones, you throw in a B-body LT1 like me and you get ..... IRON Heads which almost negate any weight savings ..... basically Im saving a bit on the Intake vs my old iron LG4 intake.

T56's weigh about 138 alone.

pasky

I shoved it on a scaled here, was 123.4 lbs. Suck it.

Sure you did, silly homo, you probably drained it for a few hours just to be able to claim it was lighter. Not to mention your scale is probably off

scottland

who cares? its like 10 pounds difference, you could get almost that by not eating the whole day.

pasky

Yea, 3.8 quarts of liquid is gonna push on 20 lbs. Then again, every scale in florida is the most accurate, hell every clock for that matter and the most important thing I forgot, your word is almighty.

EDIT: A 4L60E weighs about 200 #'s.

pasky

Just did some research, just about everywhere i check the weight of a T-56 comes out to 125 #'s.

BTW, think I found a picture of z28*****, maybe this is why yours weighed "138". Stop riding that shifter!!!

Drastius

Yea 3380 without driver

blyth18md

3296 shipping weight

1945 front
1351 rear

60/40 ratio in 82 but after a tank of gas and driver things could shift a bit


(just found rpo list today has the front/rear breakdown on it, compared it to my invoice "SW")

this is the weight with the lg4 and auto tranny and quite a few options

Air_Adam

Just for reference, a typical SBC weighs around 500lbs.

splitting hairs.....

I think 99.9% of the board was able to interpret what i was saying.....

fisherbody86

the pic of that guy riding that trans has me is the funniest thing I have seen in a while. And every post by pasky has me laughing my **** off.

pasky

*shrug*, he is the type of guy to tell you what is best and its his way or the highway so he treats everyone as if they have a lower intellgence when its him with the I.Q. you can trip over, prove him wrong and he makes some dumbass excuse like the one you saw above about my scale being off .

If an lt1 or ls1 was swaped into a v6 thirdgen would you need to replace the shocks?

pasky

If thier worn. I'd be more worried about springs.

I am running a SCCA car with a Gen1 SBC , with aluminum intake,heads,water pump and underdrive billet pulleys.

and a muncie M-21 transmission with aluminum bellhousing.

I wonder If i could save some weight swapping this set up If i swap in a LS1 backed with a T-56.

I know the LS1 is lighter, and the T-56 is heavier, I dont want to run a muncie with a LS-1 .

Can someone tell me if there is any weight savings according to their experiences

An LS1 weighs 100lbs less then a aluminum headed Gen I or II motor. Even if the T56 leaves you with the same weight it will be much closer to the center of the car.
